The boy band is reuniting after 11 years as a quartet, as Ashley Parker Angel has decided to pursue other career opportunities. Original members Erik-Michael Estrada, Dan Miller, Trevor Penick and Jacob Underwood made the announcement Monday and have since rebooted their official website.

The group, which formed during Making The Band in 2000, released two albums before breaking up four years later. Though they never matched the success of predecessors like the Backstreet Boys and 'N Sync, O-Town enjoyed success with the hit single "Liquid Dreams" and became a TRL staple.

"We started this reunion purely for the fun of it," Underwood, 33, told Billboardof their comeback. "We had discussed a summer tour to perform our old songs and finally give the fans what they've been asking us for the last 10 years. However, once we began working, what developed was something a little more ambitious. The ideas kept flying and we couldn't help but start making new music."

According to 34-year-old Estrada, this is about honoring their admirers. "Each of us have different reasons for agreeing to do this again, a decade later. Mine has to start with the fans," he said. "I never knew how much I would miss them. I never quite realized how much of an impact we had on them."

"We are blessed to be able to apply what we've learned to create something stimulating and beautiful, that we can call ours," Underwood added. "This isn't just a reunion for us. It's a new beginning."

O-Town also revealed they will be moving forward without a TV show, manager, record label, etc.

So what is Parker up to these days? After releasing a solo album in 2006 and starring on Broadway, he transitioned into scripted TV and film roles. He'll next play "a character that is extremely sunburnt, dehydrated and on the edge of death," per an Instagram caption. He's quite popular on social media, especially after he recently posted a shirtless selfie to show off his six-pack abs. "Getting to the gym 5 days a week has been challenging but it's starting to pay off," the 32-year-old wrote in the Instagram caption.
